Cleaning & degreasing

All engines are cleaned and degreased using one of our two cleaning systems, and every machined part is re-cleaned before it leaves.

The process

Cleaning & degreasing

After all machining processes are completed, cylinder heads and engine blocks are re-cleaned with a rust inhibitive detergent to remove all machining chips and honing coolant grindings.

PDM's cleaning and degreasing systems are closed-loop and self-contained, helping reduce waste disposal needs and minimise the potential for environmental contamination.

All parts brought to PDM for cleaning must be drained of all fluids — oil and anti-freeze — or a hazardous materials charge will be assessed.
